I am creating a class that will call a user defined function on user
defined intervals. In my opinion it is an error when the function
takes more as 10% of interval, or more as half a second. What is
better: just using RuntimeError, or creating two exception classes for

That is one way to look at it, Jach. Of course, a particular loop may have
multiple break statements each meaning something else. The current

I am using the C API in Python 3.8 with the nltk library, and I have a problem
with the return from a library call implemented with
PyObject_CallFunctionObjArgs.
This is the relevant Python code:
import nltk
from nltk.corpus import gutenberg
fileids = gutenberg.fileids()
sentences = gutenberg
the same way as ‘’.join, and if not then (2) how can I
strip characters from a string object in the C API?
Thanks.

The PyObject str_sentence is a string representation of a list. I need to
convert the list to a string like "".join because that's what the library call
takes.

I have a C API project where I have to slice a list into two parts.
Unfortunately the documentation on the slice objects is not clear enough for me
to understand how to do this, and I haven’t found enough useful info through
research. The list contains tuple records where each tuple consists

pDictData, despite the name, is a list of 2-tuples where each 2-tuple is a
dictionary object and a string.

Chris, you were right to focus on the list pDictData itself. As I said, that
is a list of 2-tuples, but I added each of the 2-tuples with PyList_Append, but
you can only append a tuple to a list with the extend method. However, there
is no append method in the C API as far as I can tell -- h
